Homotherium – Pain In The Bud

Paleontologists Recover Shockingly Intact Saber-Toothed Kitten Buried For 35,000 Years

The find is extraordinary, allowing scientists to directly study the extinct cat’s musculature, fur, head shape, and even its claws and whiskers.

A team in Russia stumbled on the find of the century when they located the stunningly well-preserved remains of a saber-toothed kitten in Siberia.

The kitten, which was found near the Badyarikha River in northeastern Siberia, was about three weeks old when it died, scientists estimate.

Unlike typical finds — a fang here, a mandible or partial skeleton there — this specimen still had its fur, claws, whiskers and muscles, which means scientists have already learned more about the species, Homotherium latidens, than they have with almost any other long-extinct animal.

While the saber-toothed cub is a true felid, it boasts adaptations unlike any surviving member of the panthera genus.

It has wide paws wrapped in heavy fur, a short tail and a stockier, lower-to-the-ground build than modern lions and tigers. Those adaptations, scientists believe, made it easier for Homotherium latidens to traverse environments with ice and heavy snow.

Its head shape is slightly different, with smaller ears than modern big cats, and its neck is enormous, more than twice as thick as the neck of a comparable three-week-old lion cub which was used for comparison. Likewise, its mouth is capable of opening significantly wider, although the team did not compare it to the jaguar, which has the widest-opening jaw among extant felids.

The frigid, arid clime of Siberia made it possible for the cub’s body to endure for so long. The team that made the discovery conducted radiocarbon dating that puts the cat at between 35,000 and 37,000 years old, according to reports.

It’s not clear how the cub died, although its species went extinct about 10,000 years ago, likely as a direct result of fewer prey animals in the frigid zones it occupied. Additional bones belonging to the rear of the cub skeleton were encased in a large cube of ice immediately next to the intact upper body.

The cub’s remains were recovered in 2020, but the results of the research team’s analysis were just released on Nov. 14 and published in the journal Nature. The paper’s authors have a lot more to share about the species’ physical characteristics, they noted in the text, and plan to follow up soon with a second paper going into more detail about what they learned from the cat’s intact musculature.

Like, OMG! This Kitty And Puma Are Totes Besties!

Plus: The awesome and terrifying cats and proto-cats of prehistory!

OMG, you guys! No cap, you gotta totally check out this adorbz video of a sweet widdle kitty witty becoming best fwiends with this mountain lion!

Phoebe the cat sees this cute AF puma near the back door of her home, curiously looking inside. It’s love at first sight as kitty and kitty see each other! Per Parade Pets:

“[T]he kitty in this TikTok video is completely fascinated by the big kitty outside her window. There’s no getting her away from her new friend!

On Sunday, August 25, @cricketandstrawfl shared this footage of her Tuxedo Cat posted up at the back door in their house, where a cougar was hanging out. It goes without saying that the cougar in question was many times bigger than Phoebe, but that didn’t seem to scare her at all.

It seemed like the cougar was pretty curious, too. He didn’t appear to be aggressive; instead, he was staring at Phoebe and gently pawing at the glass, trying to figure out who the tiny cat in the window was.”

OMG-hee! Look at the big kitty gently pawing at the door! He wants to give the little kitty a huggy-wuggy!

Felid predators of pre-history: They will eat you

If you’re in need of a palate cleanser after all that sugar, the BBC’s Discover Wildlife has a rundown of prehistoric cats and their particularly fascinating proto-cat ancestors, some of whom looked more classically cat-like than several species of true cats. Isn’t convergent evolution cool?

There’s the famous smilodon, the saber-toothed cat, xenosmilus, the so-called shark-toothed cat, and homotherium, the scimitar-toothed cat. Outdoing each other with increasingly sword-like teeth was apparently a big thing in the felid world back then.

There’s also the cave lion, the last of the UK’s big cats, and miracinonyx, the American cheetah, but did you know that simbakubwa, the “great lion” of Africa, topped out at almost 3,000 pounds?

Simbakubwa and dinictis were examples of “false cats.” That is to say, they were not part of the felid lineage, but closely resembled cats in body plan and behavior through convergent evolution. Nature found a niche, and several different species filled it for a time.

Dinictis in particular looks strikingly like modern big cats, which makes it even more surprising to learn it’s not part of the genetic lineage of the felid line.

Finally — or firstly — there’s proailurus, the first cat or “dawn cat,” from which all true felidae species can trace their lineage. Appearing almost 31 million years ago proailurus enjoyed napping, climbing trees and eating Temptations. Okay, we made that last part up. But still. If proailurus were around today, it would probably go just as crazy for the kitty crack as our house panthers do.

Tribe Discovers Ancient Three-Toed Cat’s Fossilized Footprint Deep In Forest

The strange footprint may date back as far as 35 million years ago, according to a preliminary analysis.

Before house cats, tigers and lions, before sabretooth cats and their scimitar-toothed relatives, Pseudaelurus (pseudo-cat) stalked the forests and plains of Europe, Asia and North America between eight and 20 million years ago.

Before Pseudaelurus, Proailurus — an animal whose name literally means “before cats” — stalked the Earth beginning 30 million years in the past.

Proailurus was thought to be the earliest true feliform ancestor, but now there may be evidence of a felid or feliform animal that predates both Proailurus and Pseudaelurus. Feliform is a term that encompasses cat-like creatures both extinct and extant, from familiar felines to civets and mongoose.

Deep in South India’s Nallamala Forest, near one of the country’s largest tiger reserves, members of the aboriginal Chenchu tribe found a fossil that could put the cat lineage back even further.

The fossil is well-preserved and clearly defined, made by an animal whose paw was about the size of an adult man’s hand. It bears a striking resemblance to tiger pug marks, but perhaps the most striking feature is its three toes.

“Based on the distinctive characteristics of the sandstone, identified as the Cuddapah subgroup Quartzitic sandstone, the estimated rock’s age is approximately 35 million years,” archaeologist Arun Vasireddy told the Times of India. “It was around this time that sandstones were formed and it is likely that the animal would have cast its prints.”

Biologists have had to reshuffle their picture of felid lineage many times over the past century and a half as new discoveries uncover previously unknown species of cats and cat-like creatures. Since they first appeared, cats have taken hundreds of different forms with significant variations in size, appearance, hunting methods and preferred terrain.

The experts aren’t popping the champagne yet. There’s a lot more work to do before they can declare a newly-discovered species or even offer more than educated guesses about its niche and appearance.

Nallamala Forest may yet hold more secrets, and research teams will look for additional prints as well as potential remains. It’s a process that will unfold over years and decades, perhaps even longer.

Still, it’s a tantalizing clue about the past and the origin of some of Earth’s most iconic animals.

In the meantime, Vasireddy said, “nothing can be said clearly until further research.”
